[Butch Cassidy Slept Here]

Wherever you fly in the world you have a choice of, at least, ten companies to choose.

First of all, when it comes to commuter cities, nothing could be further from the truth. Then what about hub cities? Atlanta: It's Delta and Air Tran/Southwest. Frankfurt: Just what is left when you take Lufthansa out of the equation? Even on a busy route like NYC (EWR, JFK) - LON (LHR, LGW, LCY) I doubt there are more than six airlines providing service of any consequence.
